Pros
Unlimited-site licensing, visual front-end editing, theme-template control, WooCommerce modules, reusable design systems, a large Divi marketplace, and a lifetime core-license option are all meaningful advantages for the right user.
Cons
Builder lock-in can raise switching costs, teams may prefer another editing model, advanced performance still depends on the wider WordPress stack, and some Pro services add recurring cost even when the core Divi license is lifetime.
For solo site owners
A single-site owner should compare editing comfort and template flexibility before over-weighting unlimited-site licensing. The lifetime option can still matter if you expect to keep the site for years.
For agencies
Agencies get more leverage from unlimited-site licensing, Divi Dash, reusable design assets and optional team/cloud tooling. The deciding question is whether the team will standardize on the workflow.
Bottom line
Divi is neither universally better nor universally worse than its competitors. It is a coherent ecosystem with unusually broad site licensing; evaluate it as a long-term workflow choice.
